To alt inkom 'it may concern: I

Be it known that I," CHARLES C. HIGGINS, a citizen of the United States, ,and a resident State of .VN ew 4 Y and Improved Vi'ndow-Lock, ofjwhich fthe following 1s a full,clear, and exact descrip-` tion.. A .i My Vinvention* relates to window locks, my more particular object being Vto provide a type ofplock in, which there yet working in unison for/'other purposes.

Reference is to be had fto the. accompanyiication, 1n which similar characters of reference indicate correspondingparts `in all the figures. f

Figure 1 is a fragmentary elevation of a window-jai`nb and its accompanying` parts, showing my improved lock inposition; Fig. 2 is a fragmentarysection` upon the `line 2 2 `of Fig. 4, lookingin the direction of the arrow and showing how myimprovedv look is used for the purpose of securing the sashes at different heights by aid of locking strips provided with bolt` holes into which one or both of the bolts are inserted;v Fig.l 3 1s an enlarged elevation of the lock with the casing removed, this view showing the plate and a lever for actuating the latter, for the purpose of forcing the bolts'back, and, if desired, for locking them in their back position by aid of a member controllable at will; Fig.. 4 is an enlarged section upon the line 4-4 of Fig. 2, looking in the direction of the arrow and showing :how the spring-pressed bolts 'are adapted to `be thrust through the locking strips in order to hold the sashes; and Fig. 5 is a fragmentary planvview of thelocking strip re-` moved from its fastenings.

The framework of a window is shownlat 6 and is provided with facing strips 6a.` The casing 7 is of metal and isprovided with ears 7a integral with'sit, for the purpose of securing it permanently in position. Locking strips 8, 9, entirely independent of each other, are each provided with a row of bolt holes 10, mating bolt holes 10,a in the sash 13, and held in position by screws 11, as`

will be understood from 2. Screws 12 extend through the ears 7 a in order to hold the casing 7 in position. Window sashes are shown at 13, 14, and are normally movablein the county ofnNassau-andy York, have .invented a :new

p are two bolts, one foreach sash, these Vbolts j being independent ofeach other for some purposes and` upper and`lower vedges respectively of the casing 7, are provided'for the purpose of holding lthe sashes' in proper position.

`an"angular boss `2O which may be engage by akey 2l for the purpose of turning the shaft. i

`Mounted within the casing 7 is a sleeve 21a 'fixed ,firmly in position and provided with guiding slots 22. `A spiral spring 23 encircles this sleeve which is provided with an annular flange 24.-". Another sleeve 25 is also lixedly mounted within the casing 7 and is providedl with guiding slots 26. This sleeve is encircled by a -spiral spring 27 which tbears against'a fiange 28 integral with the sleeve.

The springs 27, 23 respectively bear against pins 29, 30 carried by bolts 31, 32. A plate 33 Vis provided with openings 34 through which the sleeves 21a, 25 extend. The plate 33` is further provided with an arched central portion 35 which engages the upper end of the lever 17.

'The operation of my device is as follows: The operator turns the shaft 19 by aid of the angular boss 20 and key 21 for the purpose, so as to leave the bolts `either in normal position or locked, as desired. If the bolts are left in normal position, they are pressed Vupon by the springsJ 23, 27 acting upon the pins 30, 29, and when left in this position, if either sashbe moved so as to move a bolt opposite to one of the holes 10 in the adjacent strip 8 or 9, as the case may be, and the bolt holes in the sash 13, the sash having such bolt is locked, because the bolt slips into the bolt holes. In order to release the sashes, the operator yapplies the key to the angular boss'20 and turnsthe shaft 19. This causes `the finger 18 to force the lower end of the lever 17 inward (to the left according to Fig. 2). The plate 33 thereupon moves the pins 29, 30 outward, compressing the springs `23, 27 and withdrawing the bolts. If, now,

relatively to each other inthe usual manner. .Strips^1,5," 15a, terminating flush with the s Mounted centrally within the casing 7 is eoA the voperator turns the shaft 19 hard to the right, according to Fig. 2, so as to hold the plate 33 in its outermost position (to the right according to Fig. 2), it is obvious that thejlinger 18 may lock the lever 17 in this position and that the bolts are' now, Jfor the time being, withdrawn from the bolt holes and thrown entirely out of aetion.

It will thus be seen that the device above described is automatic to the extent that it may be left in such condition that a movement of either sash willcause such sash to be locked, and if both sashes' are moved, they may both be lockedand unlocked at will by the operator. It will also be noted that the device may be left in such condition that the bolts are rendered temporarily inactive, the sashes being, in such case, free to move either independently or both together.

Having thus described by invention, I claim as new and desire to secure by Letters Patent:

l. The combination of movable sashes, a casing disposed adjacent thereto, bolts mounted within said casing and adapted to be thrust outwardly therefrom, springs for actuating said bolts, pins connecting said springs with said bolts, a plate movably mounted within said casing and adapted to engage said pins, a lever for controlling said plate, and means controllable at will for actuating said lever so as to move both of said bolts simultaneously.

2. The combination of a stationary framework, a casing mounted therein, sashes movable relatively to said casing, bolts mounted partially within said casing and movable relatively to said sashes for the purpose of securing the latter in predetermined posi-j tions, a lever pivotally mounted within said casing and connected with said bolts for ac tuating the latter, a revoluble member mounted within said casing and provided with a finger for moving said lever, and means for turning said revoluble member.

3. The combination ot a stationary traineworl, a casing mounted therein, sleeves connected with said casing and provided with slots, bolts slidably mounted within said sleeve, a sash movable relatively to said stationary framework and adapted to be held in predetermined positions by aid ot said bolts, pins connected with said bolts and e.\- tending through said slots in said sleeves, springs encircling said sleeves and engagingsaid pins for the purpose ot moving said bolts into engagement with said sashes, and means for moving said bolts against the action of said springs.

In testimony whereotl I have signed nly name to this specilication in the presence of two subscribing` witnesses.

CHARLES C. HIGGINS.
